Abstract

Abstract: The effect of UV\|C treatment on the phenolic compounds and relevant enzymes activities of blueberry during fruit development was conducted. The radiation dose was 5， 10， 15 min，taking no irradiation as the control. The results showed that UV\|C irradiation could promote the accumulation of total phenols and flavonoids during development stage， decreased the CHI activity in young fruits， increased the PAL and CHI activity in other stages. And the effect of 10 min irradiation was the most significant. The activity of PAL and CHI were positively correlated to total phenol and flavonoids accumulation.

Key words: blueberry, total phenolic, flavonoid, PAL activity, CHI activity, UV\, C
